Low tps modpack server

Hello.
I apologize in advance for mistakes, but I do not know English well enough.

So yes. I have my own server on mods, there are about 80 mods. The server we have bought in OVH and we have allocated 13G framework per server. In addition, we have FastCraft but Ram usage does not increase above 5G. The server we have on the engine kclaudron forge 1614. Please help me optimize the server. There are 80 slots on the server, but there are usually over 100 players. I am asking for quick help.

I don't think you will find much help here since this is Spigot, not KCauldron or a Forge forum. Modded servers aren't easy to optimize, some older server mods are made so poorly you may as well just remove them altogether.
